你的问题写得不全。这是一道选择题，原题是：

Her second husband was _______ as rich as her first.

A. quite  B. very  C. much  D. too

此题选A (quite)。也许你的问题是：“句中 was 后是否可以用副词 quite 修饰 as...as 比较级结构？

答案是肯定的。请看例句：

He wasn't quite as perky as normal. 他并不像往常那么高兴。《柯林斯高阶英汉双解学习词典》

Working with one's head causes a sensation of hunger quite as much as muscular work. 脑力劳动与体力劳动引起的饥饿感觉是完全一样的.《现代汉英综合大词典》

▲另外，英语语法网上有一篇“使用 as ... as 结构的七个要点”的文章，文中的第 6 条就说到你的问题。
